So here's a selection of ten tech gifts that we reckon are certain to put a smile on her face. And if these don't - the adult toys we'll be covering in a few days' time as part of Reg Hardware's Sex Week are sure to.

Buying for your best bloke? We'll have a whole heap of suggestions for his Valentine's thrill on Monday.

Dodo iPad amd Kindle Fire Cases

These iPad 2 and Kindle Fire covers from DodoCase are a unique take on tech protection sleeves, cradling devices in a bamboo tray that doubles up as a stand. They also support the iPad 2's smart auto-wake system, so when the case is opened, the fondleslab powers up. And who doesn't want an über-cool hardbound book design for their slate?

The Love Me iPad 2 and Kindle Fire cases are designed by street-artist Curtis Kulid and based on his work that litters the streets of New York, Paris, Tokyo and LA. The graffiti-tagged covers could be the perfect gift for a girlfriend who prides herself on street cred.

If that's a bit too modern for your romantic side, though, the company also touts Vintage Love iPad 2 and Kindle Fire cases, which come with a more conventional style. Each one is handmade in San Francisco, though, so you'll have to be quick to get one over in time for the big day.

Enzo Zen Aroma Diffuser

Aromatherapy has always been a popular prezzie on the Day of Love, but those that come equipped with tea candles and hanging ceramic pots are so last century.

This Enzo Zen Aroma Diffuser does the job without the need for a naked flame, plugging into the wall and creating a steam fountain of scent. Simply fill her up with water, add a fragrance oil and watch the mist start pouring out. When the water runs low, the device automatically shuts down for safety.

The diffuser pumps out negative ions, which apparently make the atmosphere in a room just like the good ol' fresh air from outside - only not as bloomin' freezing. It doubles up as a soft white bedside lamp, handy when you head upstairs later. It might even be a good way to cover up the smell of old socks in case your Valentine's date accompanies you home for a coffee. Yum.
